My project passed local precheck but is getting an "exception" message during the eFabless precheck. What can I do to fix this?

it suggests to open the precheck.log file in the path. Post that too

See above

I got a similar error, and I could not pass my local precheck now. Here is the error message I got from my local precheck: {{STEP UPDATE}} Executing Check 5 of 13: Consistency HIERARCHY CHECK FAILED: Module user_analog_project_wrapper isn't instantiated in caravan.

@Mariana Huerta @Po-Chun Huang (This is my understanding of how precheck works for analog designs) Analog designs expect the user generated top level spice to be at

netgen/user_analog_project_wrapper.spice

. This file should have a top level hierarchy that matches your layout.

@Mitch Bailey Yes, I have the file

netgen/user_analog_project_wrapper.spice

, and the hierarchy matches my layout. My design can pass the precheck before the update. Is there any changes on the analog designs precheck?

I am having the same issue with the Hierarchy Check failing on the efabless platform with my analog design (passes the local precheck as well)

I also am getting the same issue and have an analog project. However my local precheck is failing too. Here is the log of my local precheck:

The same applies for me as for Po-Chun.

Ok. I think I found the problem with the hierarchy check. I don’t think there’s anything the user can do. Working on a PR. Thanks for all the information.

thank you very much @Mitch Bailey

Thank you @Mitch Bailey

Actually, looks like the caravel repo was fixed 7 hours ago. For those experiencing problems with the local precheck, can you update your caravel repo and try again? From

caravel_user_project_analog

,

make update_caravel

should work.

I'm still getting the same error. But I think my precheck is using the caravel from the docker image not the one in my project. Do you know if there is a way to set which caravel the precheck uses

Checking…

Looks like the fix works for Hierarchy check fix works! Unfortunately, I am now getting the old submodule hooks error (vccd1 connected to mprj_vccd1 instead of vccd1_core) that was happening during the September tapeout. Discussed here prior: https://open-source-silicon.slack.com/archives/C02096M650E/p1659563782526419

Hi the fix also worked for me but now I also am now getting the submodule hooks failed error. ``````

Submitted a PR to caravel and caravel-lite. Those repos will need to be updated, the retagged (requires an update to mpw_precheck too), and the precheck docker image recreated.

Pre-check is working for me now, thank you @Mitch Bailey!

also working for me, thank you @Mitch Bailey!
